Super Mario Bros. Lost Levels Walkthrough Part 6: Casual Romp

The difficulty went down even lower. I barely had any trouble with anything in this part. Well, in comparison to world 4 and 5, lol! Not that I'm complaining of course! :3

Level Time Stamps:
7-1... 0:00
7-2... 2:22
7-3... 5:06
7-4... 9:03

Enjoy!
